Hey all.  Mom's has a HP ProBook 450G1 where CD/DVD drive won't work.  It sounds like it's doing a lot of clicking and trying to run but it just won't.  I'd like to replace it but not sure what to buy.  I can only find used HP versions available.  Does anyone know if aftermarket is available?  
Thx,
Ron
